Clan Lab Indicators & Safety Information


Since 2002 New Zealand Police have located on average 200 clandestine drug laboratories a year and 68% of these were found in residential properties that were either owned by the offenders or rented. A more disturbing fact is that Police find between 70% to 85% of these clandestine drug laboratories while carrying out other duties and not even looking for them.
